Encyclopedia > Binary image

A binary image is a digital image that has only two possible values for each pixel. A digital image is a representation of a two-dimensional image as a finite set of digital values, called picture elements or pixels. ...


Binary images are also called bi-level or two-level. (The names black-and-white, B&W, monochrome or monochromatic are often used for this concept, but may also designate any images that have only one sample per pixel, such as grayscale images.) Something which is monochromatic has a single color. ... Something which is monochromatic has a single color. ... In computing, a grayscale or greyscale digital image is an image in which the value of each pixel is a single sample. ...


Binary images often arise in digital image processing as masks or as the result of certain operations such as segmentation, thresholding, and dithering. Some input/output devices, such as laser printers, fax machines, and bilevel computer displays, can only handle bilevel images. It has been suggested that this article or section be merged into image processing. ... In image analysis, segmentation is the partition of a digital image into multiple regions (sets of pixels), according to some criterion. ... This article or section should be merged with Dither An illustration of dithering. ... 1993 Apple LaserWriter Pro 630 laser printer A laser printer is a common type of computer printer that reproduces high quality text and graphics on plain paper. ... Nineteen inch (48 cm) CRT computer monitor A computer display, monitor or screen is a computer peripheral device capable of showing characters and/or still or moving images generated by a computer and processed by a graphics card. ...


A binary image is usually stored in memory as a bitmap, a packed array of bits. For the use of the term raster in radio regulation, see frequency raster. ...


Binary images can be interpreted as subsets of the two-dimensional integer lattice Z2; the field of morphological image processing was largely inspired by this view. A is a subset of B, and B is a superset of A. In mathematics, especially in set theory, a set A is a subset of a set B, if A is contained inside B. The relationship of one set being a subset of another is called inclusion. ... A collection of techniques for digital image processing based on mathematical morphology. ...


A binary image is also a compiled version of source code in Linux and Unixes Linux (also known as GNU/Linux) is a Unix-like computer operating system. ... Unix or UNIX is a computer operating system originally developed in the 1960s and 1970s by a group of AT&T Bell Labs employees including Ken Thompson, Dennis Ritchie, and Douglas McIlroy. ...

Binary Images (899 words)
Binary images are images that have been quantised to two values, usually denoted 0 and 1, but often with pixel values 0 and 255, representing fl and white.
Binary images are used in many applications since they are the simplest to process, but they are such an impoverished representation of the image information that their use is not always possible.
Binary images are typically obtained by thresholding a grey level image.
FaceBase Binary Vision Page (200 words)
Binary images are sometimes called "undithered","bilevel", or even the "raw primal sketch".
Binary images can be printed and displayed on many devices that can't process Color or Grayscale images.
Binary images are also easier, faster, and less expensive to copy, fax, and transmit.
